Converting an Array to a String in JavaScript

[Onam]

I have an array of strings in JavaScript, and I need to convert it into a single string with specific delimiter characters between the elements. Here's a sample array:

let myArray = ["apple", "banana", "cherry", "date"];

I want to convert this array into a single string with a comma and space (", ") between each element. The desired output should look like this:

"apple, banana, cherry, date"

Please send me the JavaScript code I need to do this conversion. If I wish to use a different character or characters between the array components, how can I change the delimiter? I looked for a solution by visiting many sources, but I was unsuccessful. Thank you.

It seems you would like this to happen as the result of conducting an if statement! Although, can I inquire as to what you would like to assign the variables.

If you would like to conduct an if statement, the result of the statement should prompt a change in textContent, innerText, or innerHTML, depending on user input. This is a common DOM algorithm.

<script>
if, else, addEventListener
varone.textContent="Lorem ipsum...";
</script>

use the toString command.

let myArray = ["apple", "banana", "cherry", "date"];
let text = myArray.toString();

and the array will not be changed.

Use just join(char/chars)

const myArray = [ 'apple', 'banana', 'cherry', 'date' ];
const myString = myArray.join(', '); // in this case: comma and space
console.log(myString, myArray)

BTW, check this

const myArray = [ 'apple', 'banana', 'cherry', 'date' ];

console.info('1', myArray.toString());
console.info('2', myArray.join());
console.info('3', myArray.join(','));
console.info('4', myArray.join(''));

const myArray = [ 'apple', 'banana', 'cherry', 'date' ];
const sum = myArray.reduce((sum, current) => sum + ',' + current);
console.log( sum ); // apple,banana,cherry,date

You can also just use a loop

const myArray = [ 'apple', 'banana', 'cherry', 'date' ];
let myString = '';
for (const item of myArray)
  myString += item + ', ';

myString = myString.slice(0, -2);
console.log(myString);

Another loop variant ( absolutely useless but still working )

const myArray = [ 'apple', 'banana', 'cherry', 'date' ];
let sum = '';

while( myArray.length ){
    sum += myArray.shift() + ( myArray.length ? ', ' : '' );
}

console.log( sum ); // apple, banana, cherry, date

like my example with loop for, but working as well.
